Problems solved by technology

However, for the cantilever support device of this structure, when adjusting, it is necessary to manually push the suspension wire clamp to move along the limit groove and the guide groove. During the pushing process, the suspension wire clamp has the problem of being stuck, and the suspension wire clamp is inconvenient to push and adjust. ; At the same time, the space between the suspension clamp and the adjustment bracket is very small, and the operation space when the suspension clamp and the adjustment bracket are fixed is very small, and it is inconvenient to fix and adjust.

Embodiment 1

[0028] Such as figure 1 , figure 2 , Figure 5 As shown, the suspension and fixing device for the low headroom rigid catenary busbar includes a base 1 , a rotating arm 2 and a connecting locking member 4 . In this embodiment, the base 1 is fixedly connected to the tunnel wall through the insulator 13. In actual production, the base 1 can be directly connected to the tunnel wall, and the insulator 13 is installed between the rotating arm 2 and the suspension clamp 11. between.

[0029] The base 1 includes a base plate 11 and a protruding portion 12 protruding from the base plate 11. In this embodiment, the base plate 11 and the protruding portion 12 have an integrated structure. In actual production, the base plate 11 and the protruding portion 12 can be Connected by welding. There is a ring-shaped annular groove 3 in the raised part 12, and the cross section of the annular groove 3 is convex. In this embodiment, the annular groove 3 is provided with four connecting lockin...

Embodiment 2

[0034] The structure and principle of this embodiment are basically the same as that of Embodiment 1. The difference is that in this embodiment, the inner end of the rotating arm 2 has a first positioning hole 5, and the base 1 has a protruding positioning pin for positioning. The pin is located at the center of the annular groove 3 , and the base 1 and the rotating arm 2 are positioned by the positioning pin passing through the first positioning hole 5 .

Embodiment 3

[0036] The structure and principle of this embodiment are basically the same as that of Embodiment 1. The difference is that in this embodiment, the connecting locking member 4 is a rivet, and the head of the rivet is embedded in the annular groove 3 so that the rivet and the base 1 are interlocked. Then, the rod part of the rivet passes through the annular groove 3 and the rotating arm 2 to connect the rotating arm 2 with the base 1, and the rotating arm 2 and the base 1 are fixedly connected by riveting the rivet.

Abstract

The invention provides a suspension and fixing device for a low clearance rigid catenary busbar, which belongs to the technical field of rail transit. It solves the problem of inconvenient adjustment and control of the pull-out value of the existing busbar. The hanging and fixing device for the low headroom rigid catenary busbar includes a base and a rotating arm. The base has a ring-shaped annular groove, and the annular groove is provided with several connecting locking parts that can slide along the annular groove. The inner end of the rotating arm is connected to the base by connecting the locking piece, and the rotating arm can rotate around the base, and the locking piece can be locked to make the rotating arm and the base firmly connected. The hanging and fixing device of the low headroom rigid catenary busbar has the advantage of convenient adjustment and control of the busbar pull-out value.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and relates to a suspension and fixing device for low clearance rigid catenary bus bars. Background technique [0002] Urban rail transit overhead rigid catenary suspension system, the cantilever support device is fixed on the tunnel wall to support the suspension clamp. In view of the decreasing headroom of tunnels, traditional cantilever supports are suitable for larger headrooms, which cannot meet the installation requirements of overhead rigid catenary suspension systems under low headrooms. [0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent documents disclose a cantilever support device for overhead rigid catenary in low-clearance tunnels [application number: 201910002401.3; application publication No.: CN109606206A], which includes a support base fixedly installed on the tunnel wall, a ...
